What does 235/55r17 Tire mean?

You see numbers and letters on the sidewall of a tire. What do they mean? They’re actually a detailed description of the tire’s size, type, and performance characteristics. Let’s break down the 235/55r17 tire code in a table below:

Tire NumberIts Explanation
235This is the tire’s width in millimeters (mm) from sidewall to sidewall. It means the tire is 235mm wide.
55This is the aspect ratio. It represents the height of the tire sidewall as a percentage of the tire’s width. So, a 55 means the height is 55% of the 235mm width.
RThe “R” stands for Radial, which is the construction type of the tire. Radial tires are the most common type, where the internal ply cords are positioned in a radial direction, perpendicular to the axis of rotation.
17This is the diameter of the wheel rim in inches that the tire is designed to fit. A 17 means the tire is designed to fit a 17-inch rim.

What is 235/55r17 Tire in inches?

So, we have broken down the code. Now, let’s do some converting and find out the dimensions of a 235/55r17 tire in inches, since inches are a more familiar measure for many of us.

1 inch is approximately 25.4mm. By using this information, we can convert the tire code into inches.

Table for 235/55r17 in Inches and Millimeters

Here is a handy table that represents the tire’s dimensions in both inches and millimeters. We will cover the tire’s diameter, section width, rim height, sidewall height, circumference, and the number of revolutions per mile (or kilometer). All figures are approximate.

Tire Diameter27.17690
Section Width9.25235
Rim Height17432
Sidewall Height5.08129
  • Tire Diameter: This is the overall diameter of the tire. Think of it as the height of the tire from the ground to the top.
  • Section Width: The tire’s width from one sidewall to the other. It’s like measuring how broad the tire’s smile is!
  • Rim Height: This is the diameter of the wheel rim that the tire fits onto.
  • Sidewall Height: This is the height of the tire’s sidewall, from the rim to the tread. Think of it as the tire’s profile from the side view.
  • Circumference: This is the distance around the outer edge of the tire.
  • Revolutions per Mile: This is how many times the tire will rotate in one mile.

Tire Width of 235/55r17

The tire width of a 235/55r17, as the number suggests, is 235mm. Converted to inches, that’s around 9.25. This is like the shoulder width of a small bulldog; compact, yet solid enough to take on the world! 

This width ensures that the tire has a robust contact patch with the road, enabling it to ‘bite’ the asphalt effectively. It’s the width of this ‘bite’ that allows your car to handle and respond effectively to your steering inputs. With a 235mm width, your tire is neither too wide to cause excessive road noise and fuel consumption, nor too narrow to compromise on grip and stability. It’s right in the Goldilocks zone!

Tire Height of 235/55r17

The height of the 235/55r17 tire, also known as the tire’s diameter, is around 27.17 inches or 690 mm. This diameter is larger than a regulation-sized basketball! Just imagine your car rolling along on four basketballs – that’s the size we’re talking about. A larger diameter usually means better ride comfort and improved handling, particularly at higher speeds.

Sidewall Height of 235/55r17

The sidewall height of a 235/55r17 tire, derived from the aspect ratio, is approximately 5.08 inches or 129 mm. This is about the same height as a standard deck of playing cards! 

A thicker sidewall height can provide better protection against potholes and other road imperfections. It’s the tire’s personal buffer zone – like an introvert’s personal space at a party. It helps absorb shocks and bumps, ensuring a smoother ride for you and your passengers.

Rim Diameter for 235/55r17

The 235/55r17 tire is designed to fit on a 17-inch rim, which equates to approximately 432 mm. This measurement is the diameter of the wheel itself, not including the tire. That’s around the same size as a large pizza, just less delicious. So next time you’re ordering pizza, you might want to contemplate your rims too. Although, remember, your rims might not go well with extra cheese!

Tire Circumference of 235/55r17

The circumference of a 235/55r17 tire is approximately 85.25 inches or 2165 mm. Imagine a hula hoop that size; it’s not something you’d want to throw your hip out on! 

The tire’s circumference plays a crucial role in calculating the tire’s revolutions per mile. With this circumference, your tires make around 743 revolutions in one mile. This number can influence speedometer accuracy, fuel efficiency, and overall performance.
